Trouble Finding Your Linux Game Libraries?

Some Linux games, especially the older Linux games, are installed with the versions of libraries that they need. The problem arises when the specific libraries are unknown to your system and the game won't launch.

The old Loki game installers attempted to fix this with some shell scripting. Maybe that works, maybe it doesn't. Here's an easy way to fix this problem.

First, we use a kernel utility, ldd, to see what shared libraries the binary expects to see.

$ ldd /full/patch/to/application/binary

You will get a list of libraries needed and a clear indication of whether they are present or not.

Trick #1

Assuming your system reports them missing, but you can see them in the directory where you installed the game, rather than fix the script that launches the game, we'll simply tell the system where to look.

Become root, and change directory to /etc/ldd.so.conf.d. Once there, create a file, name_of_game.conf and in that file enter 
/full/path/to/the/game/libraries.

Run the ldconfig utility,

# ldconfig

And the magic is done.

It's also possible to manually export the path every time you need to launch the game and/or put it in your .bashprofile or .bashrc, but the method outlined above solves the problem for every user of the system.

Trick #2

Some older games just require old version of libraries that must be compiled against older kernel versions. Where do we find those? We can look to the Loki Compatibility Libraries.

Download the libraries and install them in /usr/local/lib/loki.

Then, as detailed above, add loki.conf to /etc/ldd.so.conf.d and run ldconfig.

DOS4GW.EXE Version 2.01a and Alternative DOS Extenders

DOS4GW.EXE
The TenberryDOS extender DOS4GW.EXE was used by many early DOS games. I still enjoy playing many of these games and DOS4GW.EXE is usable with DOSBox, so they can be played on Linux.

However, the version of DOS4GW.EXE that was included with the game was whatever was current at the time. The most recent version that includes many bugfixes that possibly affected the games when used with DOSBox have been fixed in the latest version, 2.01a.

It's not free at US$49, but you can downloaded it here. Simply substitute it for whatever version of DOS4GW.EXE your game provided and enjoy the bug-fixed goodness. Tenberry also makes a "high-performance" "pro" version of DOS4GW.EXE, but it costs $300. I think that they could sell quite a few of these to hobby users (since, you know, DOS is dead) for US$5.

Fixing a Buggy ACPI BIOS Updated for Windows 8 and Linux Kernel 3.x

In the BIOS, there is a table that configures/determines a number of hardware values for ACPI and your system to use.

One of the features of ACPI is that the values and methods used can be differentiated at boot time depending on what OS you run. Each version of MS Windows has a unique identifier and while Linux can identify as "Linux", the Linux ACPI gurus have decided that Linux will always identify itself as "Windows NT". Even if you force Linux to identify itself as Linux, the Linux ACPI code still lies to the BIOS, except for the computers specifically listed in drivers/acpi/blacklist.

If you are running very new hardware intended for Windows Vista or Windows 8, you might get better performance on ACPI-related issues if you identify, or "spoof", your Linux OS as Vista or Windows 8. This is done by adding the boot-time kernel parameter of acpi_osi="Windows 2006" or "Windows 2012" respectively (and the quotes are necessary). still,…

Mageia

The first release of Mageia 1 is out. You can download it from here and read the release notes here.

If you've used Mandriva Linux, you'll feel right at home with Mageia. Mandriva has always had a reputation of working well for both the novice user and the power user. Installation is typically easy and hardware support is among the best of any distro. The user and administrative tools are comprehensive and easy to use. Of course, under the hood, it's all Linux and all configuration files are plain text files and all a competent administrator needs do is to choose a shell and a text editor.

Mandriva has also been known for excellent default fully-featured configurations of the KDE, GNOME, XFCE and LXDE desktop environments as well as a broad range of available applications. Mageia is no exception in this regard.

For the average user, the changes are mostly cosmetic. The Mageia art, colors and graphics are very well done (and contributed by the Mageia user community). But …
